Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description carries the full disclosure burden. It does not state that this is a read-only operation, what a finding contains, whether results are paginated or bounded, or what permissions are needed — all of which matter for a tool with zero annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single short sentence with no filler and the scope constraint front-loaded. It is efficient, though the telegraphic phrasing leaves the core subject under-specified rather than being genuinely compact.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema and no annotations, so the description should explain the shape of the returned findings and any limits. It says nothing about return contents, ordering, or volume, leaving a real gap for a retrieval tool with an optional filter parameter.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50%: site_id is documented ('Site id from list_sites') while run_id is an unannotated integer. The description partially compensates by explaining that omitting run_id defaults to the latest run, which is behavior the schema does not convey.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the resource (findings) and its scope (a site's latest run, or a specific run_id), which is more specific than the bare tool name. However, it is a noun phrase with no verb, and 'findings' is never defined, so an agent cannot tell what kind of findings these are or how they differ from siblings like get_events or get_pagespeed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The parenthetical 'latest run (or a specific run_id)' implicitly tells the caller when to pass run_id versus omitting it. There is no explicit guidance on when to call this instead of scan_site, get_events, or other sibling retrieval tools, so usage is only partially inferable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
